SWAGING MACHINE.

Application led February 20, 1920.. Serial No. 360,117.

To all whom t may concern: y Y Be it known that I, GUsTAV A. CARLSON, a citizen of Sweden, residing at Chicago, in

the county of Cook and State of Illinois,

have invented a new and useful Improvement in Swaging Machines, of which the following is a specification. l

This invention relates particularly, to swaging machines adapted to swage small shafts, or steel rods, such, for instance, as

maybe employedv in the manufacture ofV crochet needles.

The primary object of the invention is to provide an auto-matic machine ofthe character'indicated, which is simple in construction, reliabley in operation, and capable .of producing large output. The accompanying drawings illustrate a machine embodying the invention, which is capable `of loperating upon a crochet needle blank of the form shown in Fig. Il, and producing a tapered end, as illustrated in Fig. 12.

In the drawings,-

Fig. l represents a side elevational view of a swaging machine embodying theinvention in its preferred form; Fig. 2, a plan view of the same; Fig. 3, a vertical longitudinal sectional view, on an .enlarged scale;

Fig. 4, an enlarged broken transverse secy l ,equippedwith standards A2, A3, A, and A5; B, areciprocating carriage comprising tional view taken as indicated at line Aof Fig. 3; Fig. 5, an enlarged sectional view taken as indicated at line 5 of Fig. 3 .and showing the swaging mechanism; Fig. 6, an

enlarged broken longitudinal sectional view' similar to Fig. 3, but showing the carriage in advanced position and the crochet needle undergoing serves to trim the reduced end of the needle; Fig. 7, a broken transverse vertical sectional view illustrating the means for `actuating the feed device which serves to feed the needles to the chuck employed; Fig. 8, a perspective view of a cain-device employed for elevating the trimming knife and permitting the saine to drop at the proper instant; Fig. 9, a development of a cam-wheel employed; Fig. l0, a vertical sectional vview taken as indicated at line '10 of Fig. 6 and illustrating the means for automatically opening and closing the chuck; Fig. l1, a perspective View of' a crochet needle blank which is to be swaged; and Fig. l2, a perswagingoperation, this view' showing the condition at the instant preced-` ing the release of the trimming'knife, whichv spective view of the same after the swaging operation has been performed.

It may be stated here that needle blanks chuckandit's advance end is fed between an anvil-die and a rapidly reciprocating hammer-die,@by means of which the 'swaging operation is performed, the needle yrotating with ther chuck during the swaging operation; and after the swaging operation has been completed, a trimming knife drops and trims off the waste end of the needle, .after which the chuck returns toits initial position and releases the needle, which, upon the .next step of the feed-wheel, is dislodged .from the feed-wheel and dropsinto a dis-l charge chute.

In the preferred embodiment, which is a illustrated, A representsthe bed of a machine-frame, mounted on legs A', and

a sleeve B -which reciprocates in bearings vwith which the standards A4 and 4A5 are provided, and a b ar B2 which is mounted on a clamping-ring B3 secured to the sleeve B; C, a rotating shaft whichis journaled in the sleeve( B and which "reciprocates' therethe member C; C3, an automatically shifted blank, in turn, is carried forwardly by the collar which serves tooperate the levers, orl Jaws, of the chuck; D,.a lever, or trigger,

which is pivotally mounted on a hanger B4 carried bythe bar B2 of the carriage (Figs. l and 1K0) D', `a fixed cam-meniber mounted on the fra-me and serving to actuate the chuck-clamping and releasing lever D; E, a heavy standard mounted'on one end ofthe frame of the machine andserving yto carry `the swagiiig mechanism and the trimming r knife, E, a fixed swaging die (Fig. 5),

which may be termed the anvil-die; F2, a

the hammer-die, and thus serve to actuate.

the hammer die; F, a trimming knife mounted on the standard E and adapted to be lifted and dropped by means of a camdevice F actuated by a bar F2 which is.

shiftably mounted on the bar B2 of the carriage; G, a needle-blank' hopper associated with a feed-wheel G which serves to pick the needle-blanks therefrom and carry them4 into position to enable them to be gripped by the chuck, the wheel G being mounted on a shaft G2 which is equipped with'ja wheel G2, in the nature of a star wheel,

adapted to be turned in a step-by-step mamv ner; H, a trip-lever whichA is pivotally mounted on a bracket Trl carried by the'b'ar B2, and which serves to actuate. a catchdevice H2 .which forms areleasable connection between'the bar B2 of the carriage and:

the bar F2 which actuates the cam-device F for elevating and tripping the knife; K, the

main power shaft of the 1nachine;vL, a belt actuated by the shaft K and serving to actuate the pulley L which is splined on the chuck-shaft C; M, a belt actuated by the shaft K and which serves to actuate a pulley M mounted on a shaft M2, which, through the medium of a worm and .gear M2, serves to actuate a shaft M4' which extendsfparal-l lel with the shaft C and which iseq'uipped with a cam-wheel, or drum, M5', which serves. to reciprocate the carriage B; and N, a belt actuated by the shaftK andserving to actu-y ate the shaft E of the swaging mechanism.

rlhe frame of the machine may be of anyv suitable construction, and the bed A is rof suitable design to .support .the standards which carry the operative parts.

The reciprocating carriage Bis actuatedk by the cam-wheel M5, which is provided with' a peripheral cam-groove 1, engaged by .a a cam-stud 1a which depends from the member B2, which is clamped tothe tubular member' B', which thus reciprocates with the member B3. `The bar B2 of the carriage is fixedly secured to the member B3 by means of cap-screws 2. At thev front end of the sleeve B ya thrust-bearing 3 is interposed between the chuck-member C and the sleeve. At the rear end of the sleeve B', the shaft C is equipped with an adjustable bearing collar 4 and a lock-nut 42. Thus, reciprocation of the shaft C with the sleeve B is effected, it being understood that the shaft C rotates continuously in' the sleeve.

The chuck C2 comprises an internally-` threaded mounting 5 which screws on toa threaded extension in the member C; and gripping levers 5a mounted on pivots 5b carried by the member 5. The front ends of the levers 5a are suitably shaped to grip the rear end of the crochet-needle blank. Therear `ends ofthe levers 5a are provided `with camsurfacesadapted to be engaged by the shiftable collar C3. The collar C3 isfmounted to slide on the chuck-member C', and is provided with a peripheral groove in'which is mounted-a ring 6, which is provided with laterally-projecting studs 6a (Fig. l0), engaged by the-arms of a yoke 7 with which the upper endof vthe chuckclamping lever D is equipped. The lever D is supported on a pivot Srcarried byi the'V members B4 which depend from/*the front 5 end of they bar B2 of theI carriage. Thel blanks for the crochet needles are delivered by/the wheelG, iii-turn, inthep'ath' of the chuck; andy as' the chuck movesy forward; the lever Dv shifts the collar C? forwardly and causes the levers 5a to grip the rear end of the blank. In the furtherfrward movement ofthe chuck, the front end of the V blank is fed intol the dies, van'dinV the return movement of the chuck the vneedle* is,` withdrawn from the dies and ltlieflever D 'opervates to shift the collar CyrearwardlyI and eiect` release of the levers from the needle.

The cam-member D has its' lower endprovided with tworprojections 9 and 92,' the former of which engages-a projeetionzlO,

with which the member D is: provided 'as the chuck is carried forwardly, andthe latterof which' engages said projection 10 as the chuck ,isl carried rearwardly.

The standard E" preferablycomprises a heavy cast-metal member whi'clr' is 'suffrcieirtly strongI to serveas mounting for the swagingmechanism. This standard equipped withV a l,bearing-11' forthe' a'ctiiat ing shaft E6 oftheswagingi mechanism, and

1s provided with a verticalichann'el -12V through which the pitman Eworks.v The shaftv E6 is equipped with a tight pulley 135 and a loose pulley. 132; and the belt N may be shifted by' means of a belt-shifter 14.' The shaft EGk is so .geared to the shaftI Kr that said shaft E6 will rotate veryrapidly, and thus cause the hammer-die to operate rapidly. The rollers E are suitably jour-y naled in the upper end of the pitman f E4, as shown in Fig. 5. Asthe pitman reciprocates', the rollersy passwfirst above and then below a horizontal plane containing the aXis ofthe hammer-die E2 and the abutment E3, Therear end .of the shank of the hammer-die E2 is rounded, as

indicated at 15. lt will be understood that the pitman, thus equipped with rollers, acts as a wedge-member between the abutment die E2 from the die E after each impact,

andthe needle-blanklisl readily fed,-or.;

forced forward, by the rotating chuck as it advances. .The abutment E3 is adjustabley through the medium of `an adjusting screw 16.` The dies are locatedlin a suitable hori-` zontal passage, or chamber, with which the castingA E .is provided. One` wall of kthis chamber is aordedby removable plate 17 which is secured in place byl a set-screw end of theswaged needle may project be-. yond the dies.V The," knife -is equipped with a weight 20, whichconstitutes a cross-meml ber which is provided with perforadzionsy which engagethe guides 21which5exte`nd upwardly from 'the standard E. The shank` pontion of theknife is equipped .with .laten ally-projecting cam-studs- 22 which are adapted to be engaged bythe wedge-shaped cam F. The cam F comprises a cli-p 23 and arms 24 connected, by means of pin 25,

with the clip 23. The arms 24 are equipped' at theiradvance endswith inclined flanges 26, upon which the cam-studs 22 ride, in the opera-tionof lifting. the'knife. The cammembers 24 lride vupon vav surface 27 at .the upper' portion lofV the hstandard E. These members are in the form of half spear` heads,and afford abrupt shoulders 28 at the 'rear ends of the inclins; l

The clip 23 isfadjustably secured to zthe frontv end of ythe bar F2 by slot-and-screw connection 29. yThe barI F2is'mounted in a guide 30 with which the bar B2 ,ofathe carriage is equipped; `the bar B2 is further equipped with a stud, or screw,31, whichfreely engages a slot with which the bar F2 is provided. Thus, the bar F2 .may 'move with relation to the bar B2, assuming the* catch-device H2r to bevreleased. The lcatch-- device' H2 comprisesfa spring-held stud 32 whose'upper end engages'a recess 33 with which the rear end-of the barxF2`is provided. The stud is adapted to' be -released bythe bell-crank lever H, whichis mount-y ed on a pivot 34 (Figs. 1,6 and '7), carried by the member H', which, in turn, is carried byzthe bar B2 of the carriage. MThe long arm of the bell-crankleverH depends in front of the cam-wheel vM5 and is bent, as illustrated in Fig. 1.y The extremity of 'the long'arm is equipped with'a. cam-roller 35, which is adapted'to be engaged by a-caml stud 36, with which the cam-roller M5 is equipped. This engagement occurs after the swaging operation has been completed and the carriageis at the forward end of its traverse.'f Theresult isgto release the catch H2 from thebar ,F2 just afterthe centers of the of thefwedgesof the cam-members F, that is, whenthe parts are in the position shown vinvF'ig., `6. ',Thev bar F2v being thus released :from the catch H2 will bevsuddenly shifted by the weight of the knife, and the lknife will drop :and sever the wasteend of the needle. In thev return movement of the carriage, the flanges 2Gride over the studs 22 of the knife, the pivotal connections 25 permittingthe members 24 to be raised during theretur'nmovement. lWhen the carriage again .moves forward,\the weight of th .knife on the inclined portions 26 of the members F ,is 'suflicient to hold the bar F2 until' itis again latched to the'bar B2 ofthe carriage.

The hopper,vror receptacle, Gr, for they studs 22 of the'knife have passed the apex .l

S5 needle blanks37 comprises an inclined bot'-y tomI member 38, and sidevmem'bers 39. The ,l

side members. 39 are sheet-metal members which have their front lower `corners bent inwardly and upwardly, as indicatedy 2115,39a p in F'ig.- 3. Thus, there are providedinside of the front ends of the walls 39 the upturned members`392, and thesemembers arel l trimme'dto provide curved edges 391,.

The feed-wheel Grl comprises a compara'- tively narrow metal disk, which is provided in its axis i-of the wheel.` The` needle-blanks gravitate 4to' the lower; end of the hop-per and tend to bear against V.the curved edges,

ofthe anges 392. .Theperiphery of the wheel projects slightly beyond thejcurved edges of` said flanges, however, and thus the needles enter 4t-henotchesof the wheel and wheel vin the -manner illustrated in- Fig.

periphery with needle-receiving j `grooves 40, which extend parallel with the f .are elevated and carried around b-y the V 4. --fAt thefpoint wherel the needle-blank is picked up by the chuck, there is provided a pressermember 41 Vin the form of a lroller mounted in a member 41a carried by aspring 41b,`which issecured to a bracket 41. yThe roller 41 is adapted .to ride on the periphery "of the wheel as th'ewheel rotates,.and to engage the needle-blank `when rit arrives` .at the position where it is to be chucked. The wheel fG is disposed centrally between the .anges39a of lthe yhop-per, and it will thus belunderstoodthat the needle-blanks are supported yat intermediate portions by the wheel and' are@ engaged, in turn, bythe presser member 41 when they arrive at the chuckifng position. Y v

The shaft G2 of the wheel G is equipped with 'a peripherally-notched locking wheel 42, the notches ofwhich are adaptedto be engaged by a spring-pressed pawl 43 mount- Ied in a. sup-port 44. The pawl 43 is adapted toproperly center-the feed-wheel' G', that is, to insure just the proper vangular ro-tacshaft-(lf2 of the feed-WheelV G5 isfeduipped.

The principle of intermittently feeding blanks to a rotary chuckl which operates to automatically advance the blanks and rotate them while some operation is performed upon the blanks -is one which may be advantageously'employed in various situations` The improved machine is well adapted to the purpose of swaging a shaft-like 4inember, or blank, such as is used in forming crochet hooks, for example. The term shaft is used in some ofthe appended claims in the sense of -a blank, or piece of stock of this general ,character which is to be subjected to a swaging operation.

The foregoing detailed description has been given for clearness of-understanding only, and no unnecessary. limitation should be understood therefrom, but the appended claims should be lconstrued-as broadly as permissible, in view of the prior art.` y

What I regardvas new and desire to se y cure by Letters Patent is:
